Greg Stewart says he returned to Aberdeen because he has "unfinished business" with the club.

The Birmingham City striker spent the first half of the season on loan at Kilmarnock, but has switched to the Dons until the end of the season.

The 28-year-old spent the 2017-18 season at Pittodrie, scoring three times in 34 appearances.

"I just felt like I didn't do enough the first time I was here," Stewart said.

"I felt like I still had unfinished business from the time before, and to get that chance to come back again I felt like I had to take it. It was just a case of coming back and trying to put things right."
